In recent times, speedy traveling
has increased significantly with a need to meet
the dynamics of a faster business. A shift of
manufacturing bases to Asia from the high cost
developed regions of North America and Europe,
resulting in increased movement of humans as well
as materials and finished products, further calls
for low airfares. At a time when oil prices constantly
hovering over US$50 that do not show signs of
waning, and have triggered a rise in fuel cost,
causing tremendous problems for airlines all around
the World.
Newer designs of air crafts have been incorporated
using higher amount of polymeric material to reduce
the overall weight of the aircrafts, providing
some fuel economy. The light weight of the polymeric
material helps to shed almost 15 tons (5-7% of
the total weight) of the aircraft will help to
overcome problems caused by rising fuel costs.
Carbon fiber reinforced polymeric composites as
well as glass fiber reinforced material are widely
used in air crafts. Higher usage of polymeric
materials call for careful design considerations
and some modifications of the existing designs
to incorporate the typical characteristics of
this material compared to the conventional material.
In the new A 380 with a carrying capacity of
555 passengers by leading aircraft manufacturer
Airbus, polymeric material constitutes 22% of
the total weight of the aircraft. This aircraft
contains 61% of Aluminum alloys and another 10%
of steel titanium alloy.
With escalating oil and fuel prices, will the
future air crafts increase the use of polymeric
material beyond 22%? Most of the pundits feel
very confident that they will.
